Lantana plant named ‘Robpatlol’

ABSTRACT

A new and distinct cultivar of  Lantana  plant named ‘Robpatlol’, characterized by its upright and outwardly spreading plant habit; uniformly mounded plant form; semi-compact growth habit; short internodes; dense and bushy habit; freely and continuously flowering habit; and flowers that are initially yellow and become red purple in color.

Botanical designation: Lantana camara.

Cultivar denomination: ‘Robpatlol’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana camara, and hereinafter referred to by the cultivar name Robpatlol.

The new Lantana is a product of a planned breeding program conducted by the Inventor in Grain Valley, Mo. The objective of the breeding program is to create new semi-compact and freely-flowering Lantanas with attractive flower coloration.

The new Lantana originated from a cross-pollination made by the Inventor in August, 2001 of the Lantana cultivar Robpatpas, disclosed in U.S. Plant Pat. No. 13,424, as the female, or seed, parent with the Lantana cultivar Robcomplan, disclosed in U.S. Plant Pat. No. 9,837, as the male, or pollen, parent. The new Lantana was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in a controlled environment in Grain Valley, Mo., on the basis of its semi-compact growth habit and attractive flower coloration.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Grain Valley, Mo., since September, 2002, has shown that the unique features of this new Lantana are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Robpatlol have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture such as temperature and light intensity, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Robpatlol’. These characteristics in combination distinguish ‘Robpatlol’ as a new and distinct Lantana cultivar:

-   -   1. Upright and outwardly spreading plant habit; uniformly         mounded plant form.     -   2. Semi-compact growth habit.     -   3. Short internodes, dense and bushy habit.     -   4. Freely and continuously flowering habit.     -   5. Flowers that are initially yellow and become red purple in         color.

Plants of the new Lantana can be compared to plants of the parents. In side-by-side comparisons conducted in Grain Valley, Mo., plants of the new Lantana differed from plants of the female parent, the cultivar Robpatpas, in the following characteristics:

-   -   1. Plants of the new Lantana were more compact and had shorter         internodes than plants of the cultivar Robpatpas.     -   2. Plants of the new Lantana were more freely branching and         denser than plants of the cultivar Robpatpas.     -   3. Plants of the new Lantana had smaller leaves than plants of         the cultivar Robpatpas.

In side-by-side comparisons conducted in Grain Valley, Mo., plants of the new Lantana differed from plants of the male parent, the cultivar Robcomplan, in the following characteristics:

-   -   1. Plants of the new Lantana were not as compact as and had         longer internodes than plants of the cultivar Robcomplan.     -   2. Plants of the new Lantana and the cultivar Robcomplan         differed in flower coloration as plants of the cultivar         Robcomplan had yellow flowers that turned orange in color before         becoming red purple.

Plants of the new Lantana can also be compared to plants of the Lantana cultivar Robpathot, disclosed in U.S. Plant Pat. No. 12,266. In side-by-side comparisons conducted in Grain Valley, Mo., plants of the new Lantana differed from plants of the cultivar Robpathot in the following characteristics:

-   -   1. Plants of the new Lantana were more compact, denser and had         shorter internodes than plants of the cultivar Robpathot.     -   2. Plants of the new Lantana had smaller leaves than plants of         the cultivar Robpathot.     -   3. Plants of the new Lantana and the cultivar Robpathot differed         in flower color.
